DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Study reveals association between ribosomal DNA copy number and disease risk

Ribosomal DNA (rDNA) is present in hundreds of copies in the genome, but has not previously been part of genetic analyses.

Understanding public perception of polygenic embryo screening for IVF

Three out of four U.S. adults support the use of emerging technologies that estimate a future child's likelihood of developing health conditions influenced by multiple genes -; such as diabetes, heart disease, and depression -; before an embryo is implanted during in vitro fertilization (IVF), according to a new public opinion survey led by researchers at Harvard Medical School.

New technique reveals brain cells age at different rates

Engineers at the University of California San Diego have discovered that some brain cells age more rapidly than others, and they are disproportionately abundant in individuals afflicted with Alzheimer's disease.

Scientists unlock mystery behind a deadly strain of cholera bacteria

A deadly strain of cholera bacteria that emerged in Indonesia back in 1961 continues to spread widely to this day, claiming thousands of lives around the world every year, sickening millions -; and, with its persistence, baffling scientists.

Exploring how intense ultrasound can release biological indicators of disease

Ultrasound imaging offers a valuable and noninvasive way to find and monitor cancerous tumors. However, much of the most crucial information about a cancer, such as specific cell types and mutations, cannot be learned from imaging and requires invasive and damaging biopsies.

Experimental gene therapy shows promise for treating herpes infections

Researchers at Fred Hutch Cancer Center have found in pre-clinical studies that an experimental gene therapy for genital and oral herpes removed 90% or more of the infection and suppressed how much virus can be released from an infected individual, which suggests that the therapy would also reduce the spread of the virus.
